    o.k.

    so i did 1:1 278x18 and got 5.04ghz on boot & vcore at 1.68v
    mem 2.35v
    this is the error i get " WINDOWS ROOT>\SYSTEM\NTOSKRNL.EXE "
    Please re-install a copy of the above file"
    at 4.9ghz windows but after 2min it restart.
    i noties that give it more memory voltage it crash.
    2.20v this voltage stable for the memory
    this bit the hell out of me.

    u may just have got unlucky with the ram or cpu. might be worth getting another, if ur despirte for 5Ghz. if not you may have to concide defeat @ 4.8 which is still an amazing clock speed.

    targ

    So you can't raise the vcore further? That error is because the processor doesn't have enough voltage.

    o.k. when i oc 5.04ghz the vcore set at 1.68v?

    you might be right on that part about the voltage.

    on the p560 3.6ghz /D0 whats is the limit on voltage?

    because when i do 4.8ghz the processor would't boot at 1.58v
    only at 1.65v if i lower it it crach.

    Holly wow man, great OC. What FSB are you running at 4.9 273x18 ? If it boots at 4.9 and 1.65v another .03v might not help allot. Is 1.68v the highest the bios allows?
    For the p560 3.6ghz limit on voltage?

    If you know your sSpec# you can check here LINK. Just click on your sSpec#. It looks like intel says 1.4v Yours is the highest votage I've seen yet. You could also think about motherboard cooling. Putting heatsinks on you PLL clockgen chip, your MOSFET's your RAM's MOSFET's and anything ells you can find thats hot and can fit a heatsink.

    Check this out too.

    yaa my highest voltage for the vcore is 1.737v
    the system boot to 5.004ghz 1.68v but 278x18 1:1 ddr400 low mem setting.
    windows hive a error on ntosknl.exe file/ re-install file
    what i need to no if 1.7v would i burn out or kill chip.
    people are saying that the error is 560 need more voltage for
    windows to boot o.k.?
    help.

    That is WAAAY further than I'd ever ramp the vCore on a Prescott. You are probably lucky you got away with it this long!

    I'd experiment with running just two DIMMs at a time. Try them in one channel first and then switch them into the other channel. Who knows? It may make a big difference.

    Or try running a 5:4 or a 4:3 divider to see if it really is the RAM getting squirrelly.

    Did you mean to say that the DDR3's heatsinks are melting off the vid card?!?:eek: :( :rolleyes:

    I know you are running phase-change, but how many fans are cooling the case itself? More than half of the heat in a PC comes from the MOSFETs and the capacitors, you know...

    So I recommend you find out what the case's temps look like before you go any further with this; stressing the power components could be the reason you are having problems booting XP, too.

    That LN2 rig that hit 6GHz ran XP....:D

    you right i'm going to move the mem around to see if it make a diff

    ddr3 on what?

    my power supply it was 480 but change it to 600w +12/28a +5/ 52/66a
    when i change the ps it make big diff

    on fatal1ty board where are the mosfet?
    i put fan on evething that heat come from. the case is open all time one cove only.
    my room temp 26.0.c the case temp 24c

    The DDR3 on your GT...I thought you were referring to these DDR heatsinks:

    If not, then just WHAT WAS falling off due to heat?!:eek:

    the small small and small cap near the center of the vga processor.
    call nvidia support they will replace the 6800 card overnight : cool

    wow you guys are kind, i would have commented on this guy's poor grammar a long time ago. stormrayne, where are you from? and how did you get nvidia to overnight you a brand new video card after you blatantly overclocked it?

    And voila! It's the RAM. You've answered your own question.

    I saw the same error when my old DDR bit the dust...

    Just a tip since your a overclocker you can go and sign up and post for help in the Intel section in the CPU topic area. There is a dude with a air cooled P4 that he has clocked at 4.3ghz, just a basic ram upgrade helped him. You can get alot of help with your overclock, The link is http://www.ocforums.com/ anyone can go there and get help for different computer ranges.

    GL man with the Overclock just get some good DDR2 667 or something higher that is rated above DDR2 700~. Because I read on the Abit forums that the mobo you using loves good ram and do high FSB's quite nicely. The new Precotts can do some insane high clocks with Phase Change.
